'American Werewolf in London' nod

Griffin Dunne, as the doctor in one of the sketches directed by Landis, mentions that a patient in the hospital (who isnt shown) has scabs all over his body, and motions his hand along his neck to describe the scabs. Dunne, in "American Werewolf in London", as the character "Jack", was in a hospital, was full of scabs: especially along the side of his neck where the doctor referred. Maybe it's a reach but... I think this could be a slight nod to "London", which starred Dunne and was directed by John Landis.
